The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.

Participants who are ART naïve or, if ART-exposed, have not received highly active antiretroviral therapy (HAART) for at least the six months prior to study entry. All subjects will receive three doses of the HPV-6, -11, -16, -18 vaccine at the recommended dose and schedule (Day 0, Week 8, and Week 24).

Biological: HPV vaccine for strains -6, -11, -16, and -18

All subjects will receive three doses of the HPV-6, -11, -16, -18 vaccine at the recommended dose and schedule (Day 0, Week 8, and Week 24).

Participants who have been receiving highly active antiretroviral therapy (HAART) for at least six months at the time of study entry, with two HIV-1 RNA plasma viral loads < 400 copies/ml on two previous clinical visits within the 6 months prior to study entry. All subjects will receive three doses of the HPV-6, -11, -16, -18 vaccine at the recommended dose and schedule (Day 0, Week 8, and Week 24).

Biological: HPV vaccine for strains -6, -11, -16, and -18

All subjects will receive three doses of the HPV-6, -11, -16, -18 vaccine at the recommended dose and schedule (Day 0, Week 8, and Week 24).

The outcome measure for the primary objective is immunogenicity as measured by the GMT of HPV-6, -11, -16, -18 vaccine four weeks after the administration of vaccine dose #3, measured as a continuous variable. Vaccine dose # 3 was administered at Week 24.

Subjects who had a greater than or equal to (>=) 20 Milli-Merck units (mMU)/milliliter (mL) response were classified as responders; subjects who had a less than (<) 20 mMU/mL response were classified as non-responders.

Subjects who had a >= 24 mMU/mL were classified as responders; subjects who had a less than < 24 mMU/mL response were classified as non-responders.

Number of Participants With At Least One Adverse Event Possibly, Probably, or Definitely Related to Vaccine [ Time Frame: Entry, Week 8, and Week 24 ]

When a subject had at least one adverse event or sign/symptom during the study after doses 1, 2 or 3, and the event was possibly, probably, or definitely related to vaccine, this subject was considered to have had a vaccine-associated adverse event, sign and/or symptom.

Type-specific HPV DNA among subjects who were both HPV DNA negative and HPV sero-negative by study group and study visit at Week 48.

Percentage of Participants Who Reported a Lower Need to Practice Safe Sex Following HPV Vaccination and the Percentage of Participants That Reported a Higher Need to Practice Safe Sex Following HPV Vaccination [ Time Frame: Week 48 ]

Participants' perceptions for the need to practice safe sex following HPV vaccination was measured using a safer sexual behaviors subscale, which was comprised of the following five questions:

After getting vaccinated against HPV …

You feel that condom use during sex is less necessary.

You feel it is still just as important to have as few sexual partners as possible.

You feel that it is less important to talk to your sex partners about safe sex.

You think it is still just as important to use a condom every time you have sex.

You will be less worried about having unprotected sex. Those who were categorized in the "lower need for safer sexual behaviors (NSSB)" group had a summary score that was less than the median and those in the "higher NSSB" group had a summary score that was equal to or higher than the median.

To characterize young women's risk perceptions, sexual behaviors, and sexually transmitted infections (STI) diagnoses over the 48 weeks after initial vaccination, the relationship of baseline "12-item Knowledge About HPV and HPV Vaccine" measure was used to evaluate the need for safer sexual behaviors.

Visit compliance is the total number of days participants actually called the TRS or completed the VRC divided by the total number of days expected to call the TRS or complete the VRC, multiplied by 100%.

Adverse Events (AE) Reported Among Participants Who Were Randomized to the Telephone Response System (TRS) or Vaccine Report Card (VRC). [ Time Frame: Day 1 through Week 24 ]

Rate of AEs is the total number of AEs divided by the total number of participants. The rate is not a percentage bur rather it could be above 1 or less than 1. This outcome measure looked at number of AEs reported, by grade; number of AEs > Grade 3 identified; and number of AEs > Grade 3 evaluated within 24 or 48 hours.

Female

Accepts Healthy Volunteers:

No

Criteria

Inclusion Criteria:

Young women age 16 years and 0 days to 23 years and 364 days

HIV-infection after the age of 9 years as documented by a positive result on any of the following licensed tests: any antibody test confirmed by Western blot, HIV-1 culture, HIV-1 DNA polymerase chain reaction (PCR), or plasma HIV-1 RNA > 1,000 copies/ml

HIV treatment history that falls in one of the following categories:

Group A: ART naïve or if ART-exposed, has not received HAART for at least the six months prior to study entry Group B: Has been receiving HAART for at least six months at the time of study entry, with two HIV-1 RNA plasma viral loads < 400 copies/ml on two previous clinical visits within the 6 months prior to study entry

Willingness to avoid pregnancy from study entry through the Week 28 visit for subjects of child-bearing potential, i.e., use of at least one barrier or hormonal method; e.g., condoms, Depo-Provera, oral contraceptive pills, etc. Subjects on antiretroviral (ARV) medications must use a barrier contraceptive method because ARV medications can make hormonal birth control less effective.

Anticipated ability and willingness to complete all study vaccines and evaluations

Ability and willingness to participate in the study by providing written informed consent

Exclusion Criteria:

History of any prior vaccination with an HPV vaccine

Active anogenital warts within three months prior to study entry) or history of cervical intraepithelial neoplasia (CIN) 2/3 (ever, must be documented by colposcopy)

Pregnancy

Active substance use or dependence that, in the opinion of the site personnel, would interfere with adherence to the study

Presence of any known > Grade 3 clinical or laboratory toxicity at the time of study entry (per the Adolescent Medicine Trials Network for HIV/AIDS Interventions (ATN) Toxicity Tables, see ATN MOGO) with the exception of isolated Grade 3 serum total hyperbilirubinemia that is considered due to atazanavir (see Section 9.6 for definition of isolated total hyperbilirubinemia).

Receipt of any routine vaccine within four weeks prior to study entry

Receipt of any immune globulin or plasma product within six months prior study entry

Receipt of any blood product or transfusion, other than immune globulin or plasma as noted above, within four weeks prior to study entry

Receipt of any restricted medication listed in Section 5.3.2 within the four weeks preceding study entry

Receipt of any other disallowed medication listed in Section 5.3.3 within the three months preceding study entry

Thrombocytopenia or coagulation disorder that would contraindicate intramuscular injection

Receipt of corticosteroid therapy at the above dose and duration within 3 months preceding study entry. Use of non-steroidal anti-inflammatory agents and inhaled or topical corticosteroids are not exclusion criteria

Known or suspected disease of the immune system (other than HIV), i.e., malignancy, current or prior treatment for malignancy

If other serious, acute or chronic medical or surgical conditions or contraindications are present during screening, the Protocol Team must be consulted to determine whether enrollment may interfere with the evaluation of the protocol objectives and for permission to proceed with the enrollment
